I have a fairly recent version of gnuchess, and looking through the source, it struck me that the opening book is: a) very ineffiiciently represented, b) pretty much out of date, c) doesn't take into account ACTIVE and PASSIVE repertoire. Is anybody working on improving that? If not, I'll do it. -- Nicolai Czempin has no fancy .signature yet.

If not, I'll do it. I don't know if the GNU folks are working on that, but I've been kicking around my own personal ideas on how to do the representation rather than add to the existing book. My best idea is some sort of position table with hashing (to handle transpositions, since even ECO misses a bunch), but I haven't had time to sit down and make a concerted effort at doing it.

If not, I'll do it. I don't know if anyone has taken charge of this, but for my own purposes I have added an extensive coverage of the Center Game to our local gnuchess.book and am contemplating adding my rather comprehensive collection of Petrov Defense lines. (These may not interest many folks, but I have studied the Petrov for many years and am looking at the Center Game for fun. Actually, gnuchess has played some very strong and interesting initial continuations to some of the Center Game lines. Its follow-through is, of course, not as good.)
